Ok, sorry for the long delay. Holidays, work, school. You know the drill.
The Dragon Slayers are in Glantri now having just solved the mystery of the Palace of the Silver Princess (module B3).
I was going to have them go on to S4 and WG4, but instead I think it will go like this.
First I am going to have to go to the "Forbidden City" (module I1) since I worked on the Wikipedia article a lot. Then move on to the Lost Caverns of Tsojcanth (module S4) one of my favorite adventures. Here they will need to get the copy of Iggwilv's Demonomicon. Then naturally move on to WG4, the Forgotten Temple of Tharizdun and then finally ending in Death's Ride (module CM2) then moving on to Tiamat's lair for the big "boss battle". Though I am going to have to up the challenges in all the modules since the characters are now between 14th and 17th level.
What I am thinking of doing is expanding S4 and WG4 into one larger supermodule. There is so much information out there on S4 and it is a module I have owned since 1983, so I am very familiar with it. Plus there is a lot of cool things in S4 that play well into the overall arc. We need a copy of the Demonomicon and the Wonderous Lanthorn would be cool to have as would the Prison of Zagig (great place for Tiamat after the Dragon Slayers destroy her physical body).
Something to look forward to.
